Piranha

Piranha is a 1978 American B movie about a swarm of killer piranhas. It was directed and co-edited by Joe Dante and starred Bradford Dillman, Heather Menzies, Kevin McCarthy, Keenan Wynn, Barbara Steele, and Dick Miller. Produced by Roger Corman, Piranha is a parody of the 1975 film Jaws, which had been a major success for distributor Universal Studios and director Steven Spielberg, and inspired a series of similarly themed B movies such as Grizzly, Tintorera, Tentacles, Orca, Monster Shark and Great White. Piranha was followed by a sequel, Piranha II: The Spawning, in 1981, and two remakes, one in 1995, and another in 2010, which spawned its own sequel in 2012. ... more on Wikipedia
